Abstract
OBJECTIVE: To investigate the effect of acidum vitamin A on tyrosinase activity and provide experimental evidence for therapy of pigment disorder of skin. METHODS: Tyrosinase activity was estimated by measuring the rate of oxidation of DL-dopa. RESULTS: The levels of tyrosinase activity in the acidum vitamin A group were significantly greater than those of the control group (P < 0.01). CONCLUSION: Tyrosinase activity can be increasingly induced by acidum vitamin A.
